NAME:
   var - tool to fill in json/yaml stdin stream from the environment variables

USAGE:
   var < conf.yaml > env-conf.yaml

   The tool reads stdin, lookups env variables, sets them up and
   produce the result to stdout.

   All dotted("some.path.to.the.value") paths in the input file
   will be transformed to UPPERCASE and dot(".") will be replaced
   to underscore("_") to lookup the env.
   For example, env lookup for this input:

     {
       "port": 5000,
         "rabbitmq": {
         "url": "..."
       },
       "proxies": [
         "...",
         "..."
       ]
     }

   will be:

     port         -> PORT
     rabbitmq.url -> RABBITMQ_URL
     proxies      -> PROXIES_0, PROXIES_1
